Advanced NDT Services

Time of Flight Diffraction

IQI provides Ultrasonic TOFD to inspect welds of process vessel and piping. TOFD is reliable and fast advanced. In a TOFD system, a pair of probes sit on opposite sides of a weld. One of the probes emits ultrasonic pulse that is picked by the probe on the other side.

In undamaged pipe, the signals picked up by the receiver probe are from two waves, one that travels along the surface and the other that reflects off the far wall. When a crack Is present, there is a diffraction of the ultrasonic wave from the tip(s) of the crack. Using the measured time of flight of the pulse,the depth of a crack tip can be calculated automatically by simple trigonometry. This method is even more reliable than Radiographic testing of a weld.

Corrosion Mapping

The automated corrosion mapping.Automated Corrosion mapping utilizes one or more ultrasonic straight beam probes using dual X & Y axis scanner over a pipe or pressure vessel to map the thickness. These measurements are converted into colour coded images with digital wall thickness profile.

C scan can also be utilized to detect HIC, SWC, corrosion, pitting, blisters etc. Currently we have the capability to scan high temperature corrosion mapping up to 400 degree Celsius.

Electro Magnetic Acoustic Transducer

Electro magnetic Acoustic Transducer (EMAT) is a transducer for non-contact sound generation and reception using electro magnetic mechanisms. EMAT method does not require contact or couplant, because the sound is directly generated with in the material adjacent to the transducer.

Due to this couplant free feature, EMAT is particularly useful for automated inspection and hot, cold, clean, or dry environments. EMAT is an ideal transducer to generate Shear Horizontal (SH) bulk wave mode, Surface Wave, Lamb Waves and all sorts of other guided-wave modes in metallic and/or ferromagnetic materials. As an emerging (UT) technique, EMAT can be used for thickness measurement, flaw detection and material property characterization. After decades of research and development, EMAT has found its applications in many industries such as primary metal manufacturing and processing, automotive, railroad, pipeline, boilers.

Eddy Current Testing

Eddy Current testing uses the principles of electro magnetism as the basis for conducting inspections.When alternating current is applied to a conductor a magnetic field develops in and around the conductor.When a second conductor is introduced into the magnetic field an induced current flow is created.

ET is working on the principle of induced current called Eddy Current. When a current carrying coil brought into a specimen, Indicators reveal discontinuities that alter the patch of the induced currents.IQI Provides Remote field Eddy current testing unlike the impedance plane analysis form of common eddy current testing (ET). The remote field eddy current (RFET) technique is a through transmission effect that reduces problems such as lift-off normally associated with ET. In the inspection of steam generator (SG) tubes, the real issues to detect the minute cracks growing up from the outside. However, using Edit is considered infeasible to accurately find them from the inside because of the limitations of penetration of eddy currents. This describes a finite element approach to the solution of time harmonic electromagnetic fields for the RFET technique based on a magnetic vector potential and an electric scalar potential. A comparison is made of experimental and finite element predictions of electromagnetic phenomena under the inspection of non-magnetic tubes. For the cracks outside demanding high sensitive and precise measurements in the SG tube inspection, numerical results are given for parameters to design a RFET probe.

Magnetic Flux Leakage

The ultrasonic beam allows detection of metal loss from the inside

and outside of the tube wall.

Infrared Thermography

has proved to be an effective, convenient and economical method of testing concrete. It can detect internal voids laminations, and cracks in concrete structures such as bridge decks, highway pavements, garage floors, parking lot pavements, and building walls. As a testing technique, some of its most important qualities are that accurate, repeatable.

Boroscopic Inspection Service

. An internal image of the illuminated object is formed by the objective lens and magnified by the eye piece which presents it to the viewer's eye.

Alternating Current Field Measurement

IQI provides ACFM(Alternating Current Field Measurement) is used in order to identify and size surface breaking cracks in metal components.This electromagnetic technique has several benefits.ACFM may be utilized on coated materials.The coatings must be strictly adhered to the surface in order to perform the test successfully.

Also, the test can be performed if the surface contains minor scaling and debris which eliminates the need for pre cleaning prior to inspection. Test indications can be sized to show depth and length of indications .Lastly, the test can be performed at elevated temperatures as high as 900° F (Fahrenheit).

Remote Field Eddy Current Testing

IQI Provides Remote field Eddy current testing unlike the impedance plane analysis form of common eddy current testing(ET). The remote field eddycurrent (RFET) technique is a through transmission effect that reduces problems such as lift-off normally associated with ET. In the inspection of steam generator (SG)

tubes, the real issues to detect the minute cracks growing up from the outside. However, using Edit is considered infeasible to accurately find them from the inside because of the limitations of penetration of eddy currents.

A comparison is made of experimental and finite element predictions of electromagnetic phenomena under the inspection of non-magnetic tubes. For the cracks outside demanding high sensitive and precise measurements in the SG tube inspection,numerical results are given for parameters to design a RFET probe.

In-Service Inspection

Business Challenge

In-service inspections are more formally controlled by statutory requirements than other types of inspections. The ‘duty of care’ requirements are placed on plant owners, operators, and inspectors. All equipment should pass safety and compliance standards, regulations, and guidelines. Mechanical equipment can break down at any time when it is in service, which can lead to delays in production, increasing costs and liability. To prevent these situations from occurring, it is important to schedule inspections regularly.

This will ensure the equipment has been installed, operated, and maintained properly under the watch of a qualified inspector.

Shut down & Turn Around Support / Importance of Shut down Turn around in a Plant’s Operations

Plant turn around, also known as shut downs, are one of the most crucial events in the routine operation of an oil or gas plant. They also have the power to strongly affect a company’s bottom line. A turn around that goes badly, lasts for too long, or exceeds its budget could result in the company unexpectedly reporting fiscal losses. On the other hand, a turn around that goes well and stays within its budget and time-line will make a huge contribution to the plant’s efficiency and safety…setting the plant up for even bigger success in the future.
Minimizing down time in a safe Manner Every industrial plant encounters several shut downs during its life time, be it for scheduled maintenance, replacement of parts, modification or expansion. Whatever the reason, the overriding challenge is to adhere to the most stringent safety standards and keep down time to a minimum. To Achieve that goal, the whole of logistical processes– comprised of the lifting, transport, installation and removal of many components–plays an important and interdependent role. Many plants, however, were not designed with shut down activities In mind. Adding to shut down complexity is the fact that in such projects, multiple parties are generally working simultaneously at the same site. These realities call for new and comprehensive approaches that take into account not only the movement of the different components, but also the safe coordination of activities carried out by different subcontractors.
